国际标准中热应力评价标准的对比
Comparison of ISO standards on heat stress evaluation
摘要：
热应力是高温高湿条件下评价工作人员可接受环境的重要参数。详细介绍了ISO标准中涉及热应力评价的6部主要标准，深入分析并比较了这6部标准在热应力评价上的异同，并阐述了特殊应用的2部标准。对比发现，各标准评价范围、评价原理及方法、测量参数及仪器均存在一定差异。针对交通工具的评价和针对特殊人群的评价扩大了适用人群的范围，使得评价更全面，体系更加完整。介绍了我国热应力标准的发展。
Abstract：
Heat stress is an important parameter to evaluate the acceptable working environment under the condition of high temperature and high humidity. Presents six main ISO standards on heat stress evaluation in detail, analyses and compares their similarities and differences, and expounds the special application of two standards. The results show that there are some differences in the evaluation scope, evaluation principles and methods, measurement parameters and instruments. The evaluations on vehicles and special populations enlarge the applicable scope, which makes them more comprehensive and the system more complete. Presents the development of heat stress standard in China.
